4y square + y - 45 when y=-5

kobusy [5.1K]

Given:

The expression is

$4y^2+y-45$

To find:

The value of the given expression when y=-5.

Solution:

We have,

$4y^2+y-45$

Putting y=-5, we get

$4(-5)^2+(-5)-45$

$=4(25)-5-45$

$=100-50$

$=50$

Therefore, the value of the given expression is 50 when y=-5.

Can someone help me? It's urgent and thank you!

Irina-Kira [14]

Answer:

option A

Step-by-step explanation:

$\frac{x+ 3}{12x} \ \cdot \ \frac{4x}{x^2 +x - 6}\\\\= \frac{x+ 3}{12x} \ \cdot\ \frac{4x}{x^2 +3x - 2x - 6}\\\\= \frac{x+ 3}{12x} \cdot \frac{4x}{x(x + 3) -2(x+3)}\\\\= \frac{x+ 3}{12x} \cdot \frac{4x}{(x + 3)(x -2)}\\\\= \frac{1}{12x} \ \cdot \ \frac{4x}{(x - 2)} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \\\\= \frac{1}{3} \ \cdot \ \frac{1}{(x - 2)}\\\\= \frac{1}{3(x - 2) }$
